Dogs stay in heat for around 3 weeks, sometimes more. The optimal time to breed is usually around 11 days into the heat cycle. If your 5 year old Pug has never had puppies before you probably shouldn’t breed her at all. As dogs age the uterus becomes less flexible. Making birth harder on a female that is older and never had pups before. Pugs are not easy to birth even in the best conditions. If she has had litters before then you could try it once more. I usually stop breeding my pugs when they become 5 years old. Other breeds can have pups up to 6 or even 8 years of age, but Pugs are not like a lot of other breeds.
